Description

Stamping die frock for cold heading machine

Technical Field

The utility model relates to a forging and pressing field, concretely relates to stamping die frock for cold heading machine.

Background

The cold header is the equipment that is used for batch production with the mound as the owner, because part size difference, needs a plurality of parts cooperations when the mould is changed, and the dismouting process is loaded down with trivial details, and production efficiency is low. And because the difference between the large-size part and the small-size part is large, when the same clamp clamps different grinding tools, the large-size part and the small-size part are matched with a flange plate on a cold header, when a large-size die is matched with the flange, a bolt needs to be fixed on the end face, the die can be placed to a position flat with the head of the cold header only by lifting or adopting a support, and then the die is fixed from the bottom, so that the operation is extremely inconvenient.

Disclosure of Invention

For solving the above problem, the utility model provides a stamping die frock for cold heading machine uses this frock can realize loading and unloading mould convenient and fast, and easy operation is laborsaving, accords with the human-computer theory.

The utility model discloses a realize through following measure:

the utility model provides a stamping die frock for cold heading machine, includes the chuck seat, chuck seat upper portion and cold heading machine aircraft nose cooperation installation, chuck seat lower part is provided with prevents changeing the hole, prevent changeing downthehole cooperation installation chuck, the chuck side is provided with the recess, chuck seat side be provided with the connecting hole that the recess corresponds, the recess of chuck and the bolted connection for the connecting hole of chuck seat, the flange is installed in the cooperation of chuck lower part, the terminal surface is provided with a plurality of connection die's mounting hole under the flange.

Preferably, the upper end face of the flange is provided with a spigot matched with the chuck.

Preferably, the mounting holes are arranged on the lower end face of the flange in multiple circles, the diameter of each circle is the same, and the array lines of the multiple circles of mounting holes are coaxially arranged.

Preferably, the upper part of the clamp head seat is provided with threads and is in threaded connection with a cold header.

Preferably, the shape of the clamping head is rectangular, and the clamping head is connected with the flange through a screw.

Preferably, the bolt herein is a hexagonal full thread bolt.

Preferably, after the tool is assembled, the upper plane of the chuck is away from the bottom surface of the anti-rotation hole of the chuck seat by a set distance.

Preferably, the first mounting hole for connecting the chuck at the lower part of the flange is a countersunk hole, and the second mounting hole for connecting the die is a threaded hole.

Preferably, the number of the connecting holes is four, and the connecting holes are uniformly distributed along the peripheral direction of the chuck base.

The utility model has the advantages that:

1. the utility model discloses a chuck seat flange, only need pull down the bolt of connecting chuck and chuck seat during the installation mould, fill up mould and flange joint with the cushion after good, penetrate the chuck that will be connected with the mould with the bolt in the chuck seat with the side and with bolted connection fixed can to the side, convenient operation, simple swift.

2. The utility model discloses a chuck seat and chuck that set up the rectangle can play the effect that prevents the mould pivoted.

3. The setting of tang increases the transmission moment of torsion, improves the assembly axiality.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the stamping die tool for the cold header shown in figures 1-4, the upper part of the clamp holder seat 1 is provided with threads, and the threads are connected with the head of the cold header. The lower terminal surface at the chuck seat is provided with the rectangle and prevents that the hole is prevented changeing, and 3 cooperations of chuck are installed in the rotation-proof of chuck seat 1 downtheholely, and the degree of depth that this rectangle prevents changeing the hole is than the length of clamp splice dark 3mm, and the chuck side is provided with the recess, chuck seat side be provided with the connecting hole that the recess corresponds, the recess of chuck and the connecting hole of chuck seat are connected with bolt 2 of outer hexagon, and the cooperation of chuck lower part is installed flange 4, flange up end be provided with the circular tang of chuck complex, the tang degree of depth is 2mm for increase transmission moment of torsion improves the assembly axi.
